Earnings Per Share [Abstract]  
Earnings Per Share [Text Block]
—Earnings Per Share
Basic earnings per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of shares of Common Stock outstanding during the period. In addition, the shares of Common Stock issuable pursuant to restricted stock awards, restricted stock units and stock options outstanding under the 2016 Plan are included in the diluted earnings per share calculation to the extent they are dilutive. For the nine months ended July 31, 2018 and 2017, approximately 316 and 7 stock awards, respectively, were excluded from the computation of diluted earnings (loss) per share because they were anti-dilutive. The following is a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation for net income (loss) per share:
